I honestly wouldn't be surprised if this is somehow made available to the rich minority in the next ten years or so, because when it comes to exploitation, we humans are masters.
Even if we learn how to use something upto it's greatest potential, we still long for even better alternative ideas to discover even greater possibilities.
If space tourism becomes a thing (and I hope it does), it will open up a whole new set of discoveries and possibly spark curiosity in millions of young minds.
Yes, initially it will be available to the super rich. It's not due to exploitation though. Any groundbreaking technology costs A LOT, when it is initially launched. That's just the way it is. Do some research into how much launching a rocket to space costs today (even after all the progress recently by these private space companies).
But what always happens is that, over time, as more progress is made, and as more and more people are using that tech, it gets cheaper. That's just the way technology works. So, in a way, those rich dudes using it in the beginning are actually helping in the long run to make this available for everyone.
